It’s another girl for Teen Mom‘s Catelynn Lowell and her fiance Tyler Baltierra!

The parents-to-be, both 22, announced that they’re team pink at a gender reveal party this weekend. And we’re impressed with their technique: they strung a baby carriage decoration from the ceiling, pulled on a string and unleashed pink confetti. Best of all, Catelynn shared the whole thing on Instagram.

Tyler gave us a sneak peak into the festivities, which seem to have taken place at a park.

Was the big reveal a surprise for the parents too? Tyler’s caption has us thinking yes: “Today is the day! We finally get to find out if we will have a son or a daughter #Anticipation #IsKillingMe”

Gender reveal parties are a great way to have some say in celebrations for baby, since baby showers are typically planned by someone other than the mama.

This is the second child for the couple, who gave up their first for adoption.
